Before I waste my time, are you prepared to run this command:

apt-get purge sssd

You do not need sssd and it just gets in the way, you have to have
winbind running anyway.

If you are not prepared to remove sssd, then can I suggest you ask on
the sssd-users mailing list, this is because sssd is doing the
authentication (or trying to) now.
